SPECIFICATION forming part of Letters Patent No. 715,641, dated December9, 1902.

Original application filed March 5, 1901, Serial T0 all whom timmyconcern:

Be it known that I, HARRISON TAYLOR CRONK, a citizen of the UnitedStates, and a resident of the city of New York, borough of Manhattan, inthe county and State of New York, have invented a new and ImprovedHose-Cou pling,of which the following is a full, clear, and exactdescription.

My invention relates to hose-couplings, and is a division of a formerapplication filed by me-to wit, application Serial No.y 49,773, filedMarch 5, 1901. i

The invention consists in the novel construction and combination-of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawing, forming a part ofthis specification, in which the figure is a longitudinal sectional viewof the adjacent ends of two sections of an ordinary fire-hose fittedwith myinvention.

The respective ends of two adjacent sections 1 2 of hose are fittedexternally with coupling-sections 3 4 and are fitted internally withannular members 5 6. The purpose of these annular members is to preventthe hose from wrinkling or collapsing when the ends thereof are bentbackward, as hereinafter described. Thin annular bands 7 8, having aslightly conical taper, are provided for the purpose of forming a smoothsurface, thus facilitating the rotation of the clampingsection and alsofor holding the extreme ends of the hose when folded backward.Clamping-sections 9 and 10 are fitted upon the coupling-sections. Uponthe clamping-section 10is mounted a nut 11, provided with an annularflange 13 for engaging a somewhat similar but oppositely-disposedannular ange 12, integral with said clamping section 10. Theclamping-nut 11 is revoluble relatively to the clamping section 10 andis provided with screw-threads 15 for engaging the clampingsection 9.The coupling-sections and clamping-sections are detachably securedtogether, so as to prevent relative rotation thereof, by means of screws14, one or more of which may be provided. The outer surfaces of thecoupling-sections and the inner surfaces ofv the clamping-sections areprovided with screw- No. 49,773. Divided and this application ledDecember 18, 1901. Serial (No model.)

of'the clamping mechanism. The couplingf sections are each provided witha neck 19, forming a chamber 2O for the purpose of accommodating theflared or bent portion of the hose upon which the annular members 7 andSare fitted. A soft washer may be inserted between the abutting rubbersheets 18, if desired.

My invention is used as follows: The two adjacent free ends 1 2 of thehose are fitted internally with the cylindrical members 5 6 and are thenfitted externally with the coupling-sections 3 and 4. The ends of thehose project an inch or two beyond the ends of the coupling-sections.These projecting ends of the hose are then bent outwardly and backwardlyby any suitable means, so as to embrace the necks 19, and the conicalrings 7 and S are placed in position so as to hold the ends of the hosethus folded. The clampingsections are next screwed upon the coupling-'sec'tinsby'means of the threads 16 17, thus binding the flangespermanently in place. The clamping-nut 1l is now turned with an ordinarywrench, and the threads 15 thereof immediately cause the now-assembledend composed of the parts 1, 3, 5, 7, and 9 to be drawn firmly againstthe' end composed of the parts 2, 4, 6, 8, and 10. In this movement theclamping-sections do not move relatively to the coupling-sections, theclamping-nut 11 turning freely, with its flanged head 13 against theflanged head 12 of the clamping-section 10, the entire clamping-section9 movingv bodily inward toward the clamping-section 10. The result isthat the abutting surfaces 18 of the hose are squeezed together tightly,so as to form a water-tight joint. The resiliency of the hose makes thiseffect tolerably certain, even if the hose is not quite of uni- IOOvform thickness. It will be observed, therefore, that the extreme ends ofthe hose after being bent outwardly, as described, are completely sunkenin the recesses 20 and that the tightness of the joint is regulated atwill by the movements of the clamping-nut l1.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. A hose having its ends turned over or back, forminga flange, an inner coupling-section having its end beveled on its outersurface and projected into the space between the body of the hose andthe flange, a conical ring surrounding said ange, and aclamping-secltion having its end beveled on its inner surface andarranged to engage the said ring to clamp the hose-flange against theinner coupling-section.

2. A hose having its end turned back or over outwardly, forming aflange, a couplingsection provided with an end portion projecting intothe space between the body of the hose and its iiange, and au annularband on the bent portion of the hose, where its body connects with saidflange.

3. A hose-coupling comprising a pair of coupling-sections surroundingthe body of a hose and provided with necks upon which the ends of thehose are folded backward, annular members for securing said ends of saidhose to said necks, and mechanism controllable at will, for actuatingsaid coupling-sections toward each other.

4. A hose-coupling, comprising couplingsections surrounding the body ofthe hose and provided with necks upon which the ends of the hose arefolded backward, conical fastenings for holding said ends of said hosethus folded, and clamping mechanism for actuating said coupling-sectionstoward and from each other.

5. A hose-coupling, comprising couplingsections surrounding the body ofthe hose and provided with conical necks upon which the ends of the hoseare folded backward, conical rings parallel with said necks for securingthe ends of said hose thereto, clamping-sections provided with conical.portions for engaging said conical rings, and means, controllable atwill, for actuating said coupling-sections toward and from each other.

6. A hose-coupling, comprising couplingsections surrounding the body ofthe hose and provided with necks upon which the ends of the hose arefolded backward, annular members surrounding said necks for securing thefolded ends of the hose thereto, means for actuating the saidcoupling-sections toward and from each other, and annular memberslocated in said hose for preventing the same from collapsing while saidends are being folded.

7. A hose-coupling, comprising couplingsections surrounding the body ofthe hose and provided with necks upon which the ends of the hose arefolded backward, annular members located in said hose to prevent thesame from collapsing while said ends are being folded, and means,controllable at will, for actuating said coupling-sections toward andfrom each other.

8. A hose-coupling, comprising couplingsections surrounding the body ofthe hose and provided with necks upon which the ends of the hose arefolded backward, annular members located in said hose to prevent thesame from collapsing, clamping-sections mounted upon saidcoupling-sections, an annular member threaded upon one of said clampingmembers and provided with an annular flange loosely engaging the otherclamping member for the purpose of actuating said couplingsectionstoward and from each other.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
